PRICE

Published and observed billing kept separate

02

RELIABILITY

Success rate, 429 and 5xx by time window

03

COMPATIBILITY

Claude Code, Codex, Cursor and protocol checks

04

CONFIDENCE

Sample count and measurement source beside every result

DECISION SURFACES

Compare evidence,
not marketing claims.

Every result carries its source, test region, observation window, sample count and last-checked time.

Cheapest

Normalize input, output and cache prices without confusing published price with observed billing.

Open price radar →B / UPTIME

Most reliable

Compare success rate, throttling and server errors across explicit measurement windows.

Open reliability radar →C / LATENCY

Fastest

Inspect median and tail latency from a named probe region and reproducible request profile.

CODING-AGENT LAB

Compatibility is more
than a successful ping.
